REUBEN CHANEY, OF FORT NORTH, TEXAS.

VALVE-LIFTER.

Specification of Letters Patent.

Patented Apr. 19, 1921.

Application filed April 8, 1920. Serial No. 372,328.

To all whom it may concern Be it known that I, REUBEN CHANEY, a citizenof the United States, residing at Fort Worth, in the county of Tarrantand State of Texas, have invented certain new and useful Improvements inValve-Lifters; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in valve littersand has for its primary object the provision of a device that can beeasily and quickly applied and will obtain a firm and even grip on thevalve spring plate so that it can be lifted easily without the liabilityof carrying the valve upwardly with the same and which will not lose itsgripping facility on account of grease or lubricant.

Another object of this invention is the provision of a support for thetool which can be easily applied to an engine and is capable ofadjustment so that said tool can be conveniently positioned forengagement with a valve or the plate thereof.

A further object of this invention is the provision of a valve lifter ofthe above stated character, which shall be simple, durable, andefiicient, and which may be manufactured and sold at a comparatively lowcost.

lVith these and other objects in view as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described and claimed.

For a complete understanding of my in vention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa side elevation of a valve lifter constructed in accordance with myinvention and illustrating the same applied to an engine which is shownin section.

Fig. 2 is a vertical sectional view of the support.

Fig. 3 is a plan view of the tool.

Fig. 4C is a fragmentary longitudinal sectional view of the jaws of thetool.

Fig. 5 is a detail sectional view of the jaws taken at right angles tothe sectional view shown in Fig. 4.

Fig.5 is a fragmentary view illustrating a modified form of handle tothe device. 1

Rererrlng in detail to the drawing, the numeral 1 indicates a cylinderblock of an engine having a valve chamber 2 in which the valve 3operates. The valves 3 have plates 4 thereon for supporting the springs5 and which plates are limited in their downward movement by keys 6. Inorder to remove the valve 3, it is necessary that the keys be removedfrom the stems thereof and in order to do this, it is necessary to raisethe plates and compress the springs upwardly. The foregoing relates to awell lmown construction of engine to which my invent on is adapted to beapplied. A tool 7 conslsts of a pair of pivoted jaws 8 and a pair ofhandles 9 which are adapted to move the jaws toward and from each other.The jaws 8 are provided with semi-circular gripping :taces 10 on whichare formed spaced shoulders 11. The jaws 8 are adapted to receive thevalve plates and permit said plates to rest on the shoulders while thestem of the valve is adapted to pass through or between said shoulderswhen the plate is raised. The jaws 8 have the usual adjustable pivotalconnection 12 on which is formed an eye 13.

A support 1 1 consists of a shank 15 which has a hook 16 formed on oneend thereof and adapted to engage over the exhaust pipe 17 of the engineor may be placed in engagement with the cylinder block 1. The shank 15is slidably received within a casing 18 which is provided with a seriesof notches or slots 19 to be engaged by a projection 20 formed on theend or" the shank 15 whereby the casing 18 can be adjusted on the shank15 for lengthening and shortening the sup sort 1%. A hook 21 is pivotedto the end of the casing 18 and is adapted to engage the eye 13 forpivotally connecting the tool 7 to the support. After the sup port hasbeen applied to the exhaust pipe or to the cylinder block in the mannerheretofore described, the jaws 8 of the tool 7 are open so as to receivethe plate on the valve stem, permitting said plate to rest on theshoulders 11. The handles 9 are then gripped causing them to move in thedirection of each other and causing the jaws 8 to tightly grip theplates on the valve stem and then by swinging the handles 9 downwardly,the jaws 8 move upwardly causing the plates to move upwardly on thevalve stem compressing the spring and exposing the key on the valve stemso that the same can be readily removed and replaced as desired.

Referring to Fig. 6, the handles 9 of the tool are shown curved upwardlyand outwardly so they may be easily and conveniently gripped when usingthe device on a V-type engine.

While I have shown and described the preferred embodiment of myinvention, it Will be understood that minor changes in construction,combination and arrangement of parts may be made Without departing fromthe spirit and scope of the invention as claimed.

Having thus described my invention, What I claim is A valve liftercomprising a tool adapted to grip the plate of a valve, a casing de- 20tachably and pivotally connected to the tool and having spaced s1ots, ashank slidable in said casing, a projection on said shank and adapted toreceive either of the slots to adjust the shank in relation to said cas-25 V.
